Abstract

The invention relates to the technical field of soil treatment and discloses a thermal-desorption soil restoring device. The thermal-desorption soil restoring device comprises a support and a horizontal heating cylinder arranged on the support, wherein a feeding channel is arranged at the upper side of the left end of the heating cylinder, a discharging channel is arranged at the lower side of the right end of the heating cylinder, a solar heat collecting pipe is arranged at the outer side of the heating cylinder, a solar reflector is arranged at one side of the support, a main shaft is arranged in the heating cylinder, a spiral band is arranged on the surface of the main shaft, a motor for driving the main shaft to rotate is arranged on the support, an air inlet pipe is arranged at the upper side of the left end of the heating cylinder, an exhaust pipe is arranged at the upper side of the right end of the heating cylinder, an exhaust fan is arranged on the exhaust pipe, a rotary drum is arranged at the inner side of the heating cylinder, an annular space is formed between the rotary drum and the heating cylinder, and a plurality of connecting rods are arranged between the inside of the rotary drum and the main shaft. According to the thermal-desorption soil restoring device, solar heating is utilized, energy is saved and the soil thermal-desorption cost is reduced.

Description

technical field [0001] The invention relates to the technical field of soil remediation treatment, in particular to a soil thermal desorption repair device. Background technique [0002] A large amount of soil in my country has been polluted by organic pollutants such as benzene, toluene, xylene, ethylbenzene and TPH. As the public gradually understands the environmental and health hazards of organic pollutants, there is an urgent need for economical and effective methods to deal with these toxic substances. . The main remediation technologies for organic pollutant-contaminated soil include biological remediation, chemical remediation, and physical remediation. In comparison, physical remediation or chemical remediation has wider applicability, especially for high-concentration, multi-component organic pollution sites. Among many physical or chemical remediation technologies, thermal desorption is recognized as a mature and reliable technology for treating organic matter-con...
